; bugpoint-reduced testcase of MiBench/consumer-lame/quantize-pvt.c from the
; test-suite.
; It features a SCEV that is used in two BasicBlock within a non-affine
; subregion where none of the blocks dominate the other. We check that the SCEV
; is expanded independently for both BasicBlocks instead of just once for the
; whole subregion.
